Hey,
I've just updated my rrf to 3.4.5 and have been converting all the gcode to be able to use the printer again. It's a custom corexy build. However, after updating, i'm not able to home z anymore. X/Y home perfectly fine and work like a charm.
When I send G1 H2 Z5 F900, everything works fine as well. The Z axis moves away from the nozzle to the bottom where the z endstop is.
However, if i send G1 H1 Z5 F900 for homing, the print head moves in the wrong direction (up). What's even more strange, is that the y motor is also moving...This should not be a wiring issues as everything worked fine before the update, and like i said G1 H2 Z5 works fine.
I really don't see what's wrong. Hopefully somebody can help.
